真好玩的設定方式~~
你明明就請人代管DNS了~為什麼要多這2筆NS紀錄
yzcpa.com.tw nameserver = www.yzcpa.com
yzcpa.com.tw nameserver = mail.yzcpa.com.tw

我查了一下~
www.yzcpa.com 跟 mail.yzcpa.com.tw 根本沒DNS服務可供查詢~~

且 ns1.glnet.net 這台主機有幫你的 yzcpa.com.tw 設定MX紀錄給 mail.yzcpa.com.tw
dns1.glhome.com.tw 這台卻沒有~

既然你的 yzcpa.com.tw 有MX紀錄~~
你應該叫你的客戶直接把信送到 XXX@yzcpa.com.tw 就好了阿

c:\>nslookup -type=all mail.yzcpa.com.tw ns1.glnet.net
Server: www.glhome.com.tw
Address: 203.69.250.123

mail.yzcpa.com.tw internet address = 211.75.155.13

mail.yzcpa.com.tw 沒MX紀錄~反而容易出錯~~~

大大~能幫我看看我網域是否正常設定NS SOA MX 反解、查
以上紀錄是否設定正確嗎? 我去DNS Report測試 幾乎很多都通過了
只是說我主機MX紀錄只有一筆，建議設定成為兩筆，以免第一台MX紀錄
主機掛掉可以以第二台來收發信?
可是我固定IP只有一個要怎樣設定成為兩筆呢?
